I left a message the other day describing a water cooling loop I was planning to build. I now am considering adding my mobo to the loop and wanted to get your thoughts on whether or not a single pump would be enough or if I'd have to get a second pump to create either a separate loop or to run them in series.

CPU block: XSPC RayStorm Acetal
GPU block: Built-In (Apparently also sold separately)
Radiator: Phobya Nova 1080
Pump: Alphacool VPP655

Would that one pump be enough? I found some details somewhere that make me doubtful but I wanted to get the thoughts of people with more experience. My understanding is that the typical motherboard block adds a lot of resistance to the system.

the alphacool pump is a rebranded Laing D5. great pump ( I have the swiftech branded one myself ) it can handle an entire loop along with motherboard. keep in mind though, putting the board under water is for aesthetics only. Also I should mention that yes motherboard blocks tend to add more restriction than cpu and gpu blocks, the pump should have no trouble handling it.

it might be, but i would go with 2 to be sure. unless you are experiencing extremely high mobo temps and you have bad airflow, water cooling your mobo is overkill. here is an awesome guide to water cooling: http://www.youtube.com/watch?v=JtHDqdo5pR0

Thanks for your help guys. I'll leave the motherboard out of the loop for now and only add it should I find a need for it later. I don't think airflow will be a problem with the case I'm using (Phantom 630) and I can always add a fan specifically for the motherboard. Going to give Hard Line the solution since his came in first.

Tthe 1080 rad can more than handle everything you plan to do. and going separate loops will only decrease temps by 1-3C. IMO not worth the hassle.

For comparison, I am running 2 gpus and cpu on 1 Swiftech 655 vario running on setting 4, an rx 480 and rx240. temps are crazy low and only 67C full load prime 95 AND kombustor i7 930 @ 4.45ghz.

Yeah, I switched to this radiator after discussing that very issue in the question I had posted previously. I had originally planned for the Phobya 400 but got advice to go with something a bit bigger and with support for better fans. I figured I'd rather just get one rad that can handle everything in a single loop and avoid the hassle of dual loops.
